Compressive membrane action in circular reinforced slabs

The elastic-plastic Deformation Theory solution for circular concrete slabs has been worked out. The resulting graph never touches the curve for rigid-plastic strain-rate solution as it does in the strip case, Eyre (Journal of Structuring Engineering 1990;116(12):3251; 1997;123(10):1331). However, the maximum membrane force at the centre may still be used to derive an explicit load capacity as a function of material properties and restraint stiffness only.
